"United States Patent 3,467,001 PAPER SCRAP PICKUP AND BALING MACHINE Valentino L. Balbi, 52 W. Market St., Daly City, Calif. Filed Oct. 16, 1967, Ser. No. 675,410 Int. Cl. B30b 15/30, 15/20; B60p N00 US. Cl. 100-74 Claims ABSTRACT OF THE DISCLOSURE My present invention relates to scavenging and more particularly to an improved automotive truck for picking up paper scrap.

At the present time this scrap material, as accumulated by metropolitan retail stores, comes to quite a sizeable chore when set out for pick up at curb side in burlap sacks or the like which are then carried away in a truck for final disposal. A primary object of my invention is, therefore, to provide a truck for scavengers by which scrap paper, cardboard boxes and cartons may be picked up and formed into compact bales at curb side for final disposal at a more distant point.

At the present time scrap materials of the above character are accumulated by the retail stores and wrapped by them in burlap sacks or the like and are picked up in this form by the scavenger for final disposal. In this operation, however, the sacks and wrappings of such material soon amounts to a full truck load and, consequently, the daily collection of this material requires many trucks with frequent trips to the disposal point. It is therefore a further object of my invention to provide a truck with means by which the scrap material as picked up at curb side may be conveniently formed into small bales which will result in a considerable reduction in the size of the truck load for each trip and thus result in considerable economy in this operation.

Other objects and advantages will be in part evident to those skilled in the art and in part pointed out hereinafter in the following description taken in connection with the accompanying drawings wherein there is shown by way of illustration and not of limitation a preferred embodiment of the invention.

In the accompanying drawings wherein like numerals refer to like parts throughout the several views,

FIGURE 1 is a side elevation of a truck constructed in accordance with the invention,

FIGURE 2 is a fragmentary, larger view partly in section and showing details of construction,

FIGURE 3 is a view similar to FIG. 2 taken in a plane at right angles to the plane of FIG. 1, and

FIGURE 4 is a fragmentary sectional view taken along line 44 in FIG. 3.

Reference is now made to the accompanying drawings for a more detailed description of the invention. As shown in FIG. 1, my invention contempaltes a truck designated generally by the numeral having a conventional drive with a cab 11 at its forward end. Behind the cab 11 the truck 10 has a load-carrying area 12 into which bales of refuse designated by the numeral 13* may be stacked as, shown by dot and dash lines. At the rear end of the truck and in overhanging relation there is a refuse baling means having a vertically disposed rectangular re- "ice fuse accommodating chamber 14 with a side opening closed by a door 15 which when open will form a chutelike entrance into the vertical refuse accommodating chamber 14. Extending horizontally and having its interior in communication with the open upper end of the vertical refuse accommodating chamber 14 there is a second refuse accommodating rectangular compacting chamber 16 having a piston-like member, not here shown, by which the refuse initially compacted in the vertical refuse accommodating chamber 14 will be further compacted to complete the formation of a bale of the refuse discharged thereinto from the vertical refuse accommodating chamber 14. When thus finally compacted into bale-like form the compacted bale will be finally discharged at the inner end of the horizontal refuse compacting chamber 16 for stacking on the truck as indicated. The vertical refuse accommodating chamber 14 has a stirrup-like piston member which, as will be hereinafter described, is operated by two oppositely arranged hydraulic means 17, and at the inner end of the refuse compacting chamber 16 there is a bale discharging opening 18 with a closure means 19 that is raised and lowered by hydraulic means 20 for handling the bales as they are formed.

Reference is now made to the remaining figures of the drawings wherein it will be seen that the vertically extending rectangular refuse compacting chamber 14 is of square cross-section while the horizontally extending refuse compacting chamber 16 is of rectangular crosssection, being of a width slightly greater than the area of the refuse compacting chamber 14. Mounted within the horizontally extending chamber 16 there is a rectangular piston 21 with a skirt-like portion 22 that will operate as a bulkhead at the upper end of the compacting chamber 14. For operating the piston 21 there is a hydraulic means 23 by which is first moved to the left to permit the entrance of compacted material from the chamber 14 and when moved in the opposite direction it will operate to further compact the refuse discharged from the chamber 14. As a final operation the bale as thus compacted by the piston 21 may be removed from the chamber 16 through the opening 18 by the operation of the hydraulic means 20. At this point it will be noted that the hydraulic operating means 20 is carried by a dolly 24 which will permit a compacted bale upon the member 19 to be carried to the right for the application of bailing wires should this be found necessary. The hydraulic means 17 operating along opposite sides of the refuse compacting chamber 14 are mounted upon brackets 25 and at their upper ends they engage overhanging portions 26 formed as a part of piston supporting arms 27, which as previously stated form a stirrup-like supporting means for a refuse compacting piston-like member 28. As shown in the drawings the member 28 is adapted and arranged to operate from the bottom of the refuse compacting chamber 14. At opposite sides of the refuse compacting chamber 16 there are suitable guides 29 through which the upstanding arms 27 are guided in their upward movement. In this particular showing the upstanding arms 27 are of T cross-section and at their lower ends these arms 27 connect with outwardly extending fins 30 that will move in slots 31 formed in the sides of the refuse compacting chamber 14. When the refuse compacting member or piston 28 is in its lowermost position and the closure door 15 is open as indicated by dot and dash lines the refuse may be initially deposited in the chamber 14 above the member 28. After the door 15 is closed the compacting member 28 will carry the refuse up into the chamber 14 where it will be initially compacted against the skirt 22 of the piston 21. Following this and upon a retraction of the piston 21 the refuse will be into the horizontal refuse compacting chamber 16. Then by a reverse operation of the piston 21 the refuse will be compacted in the chamber 16 above the opening 18 at the far end thereof. During this final movement of the piston 21 it will be understood that the skirt-like portion 22 of the piston 21 will provide a bulkhead as previously suggested at the upper end of the vertically extending refuse compacting chamber 14. The compacted bale can then belowered upon the member 19 and carried free of the chamber 16 for stacking on the truck. While my invention may be used for baling various forms of refuse, it is primarily intended for picking up waste paper, corrugated cartons and boxes, which by their very nature possess an ability to absorb water and therefore to facilitate a tight compacting of such material I have shown the vertically extending refuse compacting chamber 14 as having sprinkler means 32 at its sides through which water will be sprinkled over the refuse as itis deposited at the lower end of chamber 14. With refuse of the character contemplated and wetted in the above manner it will be readily seen that the compacted bale Will take the form of a highly compressed pulp-like mass that will retain its shape throughout the compression stages of the baling operation and while such bales, still moist, may be handled as a unit it is conceivable that where storage time is involved, baling wires or bands may be applied to the bale as it is carried from the chmaber 16 upon the closure means 19 as above indicated.

While I have shown the hydraulic means 17, 20 and 23 as formed by telescoping cylindrical members operating in the conventional manner by hydraulic power, it will be understood that this hydraulic means may take other forms such as will suggest themselves to persons skilled in the art.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
